The order Lepidoptera, with about 160,000 described species, has a great ecological and chromosomal diversity, representing an excellent model for studies of genomic organization and evolution of repetitive DNAs and their relationship with karyotypic evolution. In addition, this group is extremely important from economic point of view, as several species are pests in the agricultural envi…
The satellite DNAs (satDNA) are repetitive sequences organized in tandem, forming in general large arrays and comprising large portion of eukaryote genomes. They are peculiarly enriched in heterochromatic regions, mainly in centromeres. These sequences play role in chromosomal structure and recently functionality for them has been described. The genomic and chromosomal organization and th…
The analysis of experimental models for knowledge of sex chromosomes evolution progressively advance and currently the molecular cytogenetic and genomic data has been explored for this proposes. In crickets and in some grasshopper species wide diversity of sex chromosomes systems have been observed, occurring X0/XX, neo-XY/XX, neo-X1X2Y/X1X1X2X2 and X1X20/X1X1X2X2, originated by distinct …
With the aim of acquiring deeper knowledge about repetitive DNAs chromosomal organization in grasshoppers, we used fluorescent in situ hybridization (FISH) to map the distribution of 16 microsatellite repeats, including mono-, di-, tri- and tetra-nucleotides, in the chromosomes of the species Abracris flavolineata (Acrididae), which harbors B chromosome. FISH revealed two main patterns: (…

The order Hemiptera, encompassing true bugs, is a vast group constituting the fifthlargestinsect order with nearly 107,000 species. Within Hemiptera, the suborderAuchenorrhyncha, specifically the family Membracidae, is notably diverse andmorphologically varied. Membracids, like other Hemipterans, exhibit holocentricchromosomes which are characterized by the lack of a single, localized cen…
Eukaryotic genomes are complex in composition, functioning and evolution. Part of this complexity is due to the large proportion of repetitive DNAs, besides the occurrence of sex chromosomes. The study of repetitive DNAs and sex chromosomes, as they have accumulated this class of DNA, is complex and neglected in most genome assembly projects. Moreover, it is known that genomic aspects can…
The essential set of chromosomes of individuals form the A complement, which include autosomes and sex chromosomes. However, in several species the presence of extra chromosomes or B chromosomes has been documented. These chromosomes are not an essential part of the genome, but it has already been noticed that their presence can cause changes in cell metabolism, altering the gene expressi…
Repetitive DNAs comprise large portion of eukaryotic genomes, playing role in their structure, evolution and functionality. Studies of this genome fraction are negligence in projects of genome analysis due to the difficulty to assembly. B chromosomes are supernumerary elements, enriched of repetitive DNAs, which could be transcribed and have interference in functional aspects to their hos…

The family Crambidae (grass moths) includes approximately 11,000 species and thus represents one of the largest families of the insect order Lepidoptera. Several species of this family are particularly well known due to severe economic losses in agricultural production. In Brazil, some Crambidae species such as Diatraea saccharalis, D. flavipennella and Omiodes indicata have been causing …
Orthoptera insects have a wide range of sex-determining systems including X0, neo-XY, neo-X1X2Y and X1X20, that putatively has independent origin and evolution with distinct degrees of heteromorphization, heterochromatinization and repetitive DNA accumulation. Although this diversity of sex determining systems has been extensively studied at the cytogenetic level, little has been analyzed…
